Please help me!!!! Anyone pleaseeeee!!!

otez555 [7]

Answer:

69 degree

Step-by-step explanation:

Using cosine formula again :))

So we have

BC^2 = AB^2 + AC^2 - 2*AB*AC*cosA

BC^2 = 32^2 + 28^2 -2*28*32*cos56

BC = 28.3884 cm

So B:

AC^2 = AB^2 + BC^2 - 2*AB*BC*cosB

CosB=0.3559

B=69.14 degree

ANSWER

The explicit formula is :

$a_n = 8+ 3(n - 1)$

EXPLANATION

The given sequence is

8,11,14,17,20,23,26,...

The first term is

$a_1=8$

The common difference is

d=11-8

d=3

The explicit formula is given by:

$a_n = a_1 + d(n - 1)$

We substitute the values to get,

$a_n = 8+ 3(n - 1)$
